Just a brief update with Thetis v2.6.2 and Orion_NP_v1.3_TEST1.rbf firmware: I've been using Thetis for 5 hours straight and running it hard on 75 meter AM (without PS enabled) and 20 meter SSB (with PS enabled) and it has been very well behaved. I have not strayed from a sampling rate of 192 kHz ye...

Scott, ***I can confirm that Audio L/R is swapped compared to OpenHPSDR v3.4.9 ***My RX-2 is working fine with good sensitivity through either ADC0 or ADC1. However, it looks like RX-1 and RX-2 are using DDC2 and DDC3 and I think OpenHPSDR uses DDC0 and DDC1. So... if someone is not aware of that th...

Rick, Thank you for posting the 1.3 TEST version of the firmware. This is the first protocol 2 firmware version for me where Pure Signal works perfectly from 160 through 6 meters with my 200D! I have to admit that after testing it on all bands into the dummy load that I have not yet made any contact...

I would echo that I also experience the disappearing PS issue that Jeff has outlined above. My 200D (FW 1.3) running Thetis 2.6.1 will run fine for several minutes and then PS will simply stop correcting. Sometimes it will resume on its own but other times it will get quite stubborn and require inte...

Scott, I have used P2 firmware v1.3 and Thetis v2.60 with my 200D for casual operation on the 160 and 75 meter bands and it has been stable there. The Pure Signal protocol does not work well on 40 meters (AmpView displays a very confused looking graph) and on 20 meters and above it does not work at ...

Ed, Back in 2014 when I first had my ANAN-100 there was an issue with low power output on 12 meters if the firmware version that was released for the TAPR Hermes board was used with the ANAN version of Hermes. Typically, within a few days of a firmware release Abhi would re-map the LPF in the firmwa...

Thanks for the M.2 SSD name for these slot-mounted drives. A 5X speed boost is a very significant performance improvement! I can feel that urge beginning to take hold to build another "fire breathing beast".

Nice build Clyde! It's great to have all that horsepower under the hood and also fun to watch it rip through any task you throw at it without flinching. It always amazes me how quickly computer hardware changes. Things like the newer SSD form factor that has changed so that now you can buy models th...

Just an update on the resolution for the program stalling problem I was seeing with SDR Console. As it turns out, in the Windows 7 firewall settings there was a second entry for SDR Console that was blocking it from responding to the keep-alive "ACK" packets. Once the settings in that seco...

I kind of like the natural sounding two-tone (700Hz + 1900Hz ) "Song of Our People" and will tune right to it when I hear it on any band! It helps me to avoid signals like this newest addition to the "Dirty Dozen Hall of IMD Infamy"! The guy displayed in the screenshot below was ...

David, Don't be too discouraged at this point in the development process. Apparently, there are still some timing closure issues and logic errors that are being chased out. At this time, my own 200D is not fully functional with the Protocol 2 firmware so I am also a member of the club that's looking...

Carl, It was nice to catch you yesterday on 20 meters. Although we only chatted for a few minutes I was actually listening most of the time you were on the air and it looks like tightening up the loose hardware has corrected the issue. I didn't hear any anomalies or observe any blow-outs in the pana...

Ben, I just installed the Hermes VNA software and it runs fine on my Windows 7 computer. It connected right up to my ANAN-200D on its little private subnet and patiently waited for me to figure out how to run a simple plot. I ran the calibration procedure (open circuit, short circuit, 50 ohm termina...

Hi Ben, I did not reply immediately to your post because I hoped that someone might have more information than I have. I have not personally used the software at the link below with either my ANAN-100 or my ANAN-200D but perhaps others have, or maybe Phil VK6APH will jump in with comments on the sta...

I use the rear panel DB25 for PTT with my 200D: Connect one lead to pin 13 (PTT) Connect one lead to pin 21 (Analog Ground) When the connection is closed between those two pins you will transition from RX to TX. Note that pin 25 (Analog Ground) can also be used for the ground pin instead of pin 21 i...

Hi Mark, I believe the Angelia board MIC jumpers are in the same area as the Hermes MIC jumpers, right behind the 1/8 inch input jacks. With my ANAN-100 that I sold last year it was about a 15 minute job to drop the front panel and reach in with tweezers to arrange the jumpers as needed. Add another...

Hi Bill, Keep an eye on the ATT field down at the lower left of the GUI. I think above and below 15 MHz you will see a different attenuation level by default when you tune either lower or higher than 15 MHz. If you set the 15 MHz ATT level to the same as 14.999 and 15.001 the RX behavior should be t...

Hi Joe, I'm not as good looking as Scott but I can answer this one: The HPSDRProgrammer (version 2 nopcap) utility is the most convenient for flashing any protocol 1 firmware to another protocol 1 version. You can also use the HPSDRProgrammer to flash from protocol 1 to protocol 2, however, it is un...

Hi Gary, I never tried directly editing the RX frequency in the chart as you have described, but I brought up my Memory chart in OpenHPSDR and found that if I only edit the RX Freq column, it behaves exactly as you stated. The entry in the chart changes, but the actual received frequency does NOT ch...

That was quite a project Scott! You were really thorough and the 30 degree drop is a nice payback for the effort. Nicely done! Although my cooling projects are not in the same league as your efforts, I have found with my gaming and radio computers that I have to remove my CPU coolers about once ever...

Glad you have it sorted out Tony. Yes, when I have not used the playback feature for awhile I nearly always forget to set the PTT override for VAC. It provokes one of those hmmmmm.... moments but I suppose it's good for the brain!

Hi Tony, From your screenshot, it looks like you may be playing back an audio wav file while in receive mode. The PowerSDR mRx PS audio wav playback and quick play functions are only intended to play audio files while in transmit mode. My screen looks similar to yours if I play an audio file through...

Hi Tony, If it sounds fine when playing it back on the PC then it most likely is the TX Gain setting in the "Wav File Controls" form. I can't recall what the default setting is but I do recall that I had to reduce the gain significantly to get the audio level close to the level of my audio...

Hi Chuck, I believe you can identify whether it is a 10 or a 10E by looking at the firmware version in the Hardware Config menu tab of OpenHPSDR. The ANAN-10 firmware will be in the 3.x series which is also used by the ANAN-100 rigs. The ANAN-10E firmware will be in the 1.x series which is also used...

Very nicely illustrated Scott, and it should be helpful to anyone running audio into the ANAN's 1/8 inch TRS MIC jack. When running a balanced microphone (typically found with studio dynamics) into an unbalanced input (like what is found with the 1/8 inch TRS jack of the ANAN rigs) I have always use...
